First some things I don't like and then few additional facts on what's done well to decide if this game is for you. Game looks good and technically is at par with the previous title of the series but there is one huge design decision which ruins the whole game from me. You are traveling with a companion who saves you every damn time you make a "lethal" mistake and saves you back to the closest platform you stood on. Instant spawning can make the whole game a series of trial and errors instead of well thought out actions. You can just run into a new place and try to improvise and fall into every single gap couple of times until you end up with a gap which requires some brain power. Same thing with fights, the companion just heals you if you take too much damage... Also fighting mechanic has been simplified from the previous 2 titles but is still better than on the 2003 game. You probably like this game if you like the following: the graphics, looks quite good if you like the cartoon style collecting, tons of orbs to collect (especially if you like to see some effort to 100% a game) progression, you can choose which unlocked area to go next for bosses, the battles are always quite different (if I remember right, been a while ^^") short check-points, every single platform you can stand on acts like a check-point 10-15 hours of gameplay, you'll prolly won't be re-playing this one though This game is perfect for many kids who think some games are too challenging and people with short temper. If you like hard games do not bother. If you are still interested. Make sure to watch enough gameplay footage before buying.
I can remember this game being not that good and quite difficult but it still has tons of sentimental value so I'll let it slide to some extent. Get it only if you played the original release back in the days and didn't break your disc to put out some steam =P Or just prepare to buy only a decent game you might like just enough to complete it or simply never try again after first boot. Big risk but you are only betting a fiver so it can't be that bad if you feel like trying it.
